Cool San Francisco ranch house is a sustainable gem

Plastic is probably in your food or drinking water, and now scientists fear it might be flowing through your veins.  A small study published last month found that the blood of 17 out of 22 people contained microplastics — plastic fragments smaller than a sesame seed. It’s the first time those tiny bits of fossil-fuel product have been detected in human blood, but the discovery is no surprise to plastics researchers.  “Plastics are everywhere,” Rolf Halden, the director of the Biodesign Center for Environmental Health Engineering at Arizona State University, told Insider.  Previous studies have found microplastics in humans’ food, drinking water, poop, placentas, and lungs, and drifting through the air we breathe.
